Although Hubbard filled a variety of positions in the forward line, it was his ability as a nippy right-winger that prompted the Tigers to sign him from near neighbours Scunthorpe. At Scunthorpe, his prowess at scoring goals had attracted attention from other clubs but his record with the Tigers got off to a slow start, scoring only 4 goals in 37 appearances during his first season. His versatility did not help in this respect but once he settled down to a regular slot on the right flank his tally improved. It was this improvement, climaxed by 21 goals in 43 appearances during the 38/39 season, that resulted in a move to West Ham. Howieson continued his goal scoring exploits with the Hammers but it was cut short by the outbreak of WW2. During the war Hubbard played for a number of clubs as a 'guest' including Barnsley, Nottm Forest, Huddersfield and the Tigers (7 apps.). After the War his career resumed in junior football with Goole Town and Worksop Town. It was with the latter club that he also had a spell as coach in the early 60's prior to his death.
